A motorcyclist was injured on Interstate 205 in Gladstone early Wednesday, when a man driving an SUV allegedly fell asleep, lost control and crashed into his motorcycle.

Bruce Melbourne Becker, 63, of Vancouver was rushed by ambulance to OHSU Hospital, where he was in serious condition.

Christopher Mark Pearson, 49, of West Linn was cited on an accusation of careless driving.

Lt. Gregg Hastings, Oregon State Police spokesman, said Pearson was driving a Jeep SUV north on I-205 near Milepost 12 around 5:15 a.m., when he fell asleep. The Jeep then drifted to the right, crashed into the guardrail and bounced to the left, hitting Becker's motorcycle in the center lane.

Hastings said Becker was wearing a helmet. Pearson was not injured.

The crash shut down the highway's northbound lanes for nearly an hour. Clackamas County sheriff's deputies, Clackamas Fire District 1, the Oregon Department of Transportation and American Medical Response ambulances also responded to the crash.
